To integrate a solution like this with Squid you need to have some web page doing the question thing and registering the client station as "trusted" in a file or DB, then use and external acl to have Squid query this registry and deny_info to redirect the user to the "question page" if no active session is found. Note: max_user_ip restricting the user to a single IP at a time is probably about just as effective. Especially with a long TTL. Regards Henrik
